将管理敏感数据备份的工作委托给声誉有问题的公司会带来高风险。此外，对于某些不知名的人访问您的数据的恐惧总是很严重。幸运的是，可以使用一些在线备份服务和必要的步骤来确保您的数据保持私密性和适当的安全性。在这篇文章中，我们将介绍 5种免费在线备份服务(Free Online Backup Services)。
在基于云的在线备份(Online Backup) 服务(Services)中寻找什么
提供的空间量是最重要的方面之一。有许多付费选项专门用于使用HTTPS(HTTPS)传输备份数据，但本文将忽略它们，因为我只打算使用免费选项。大多数在线备份服务提供高达 2GB 的免费数据。
我在这里不算OneDrive 或Google Drive ，因为它们更多的是协作和共享工具。此外，它们不提供加密，这是备份数据时的另一个重要因素。Mozy、Adrive等提供加密，因此即使远程服务器被黑客入侵，您的数据也是安全的。云服务总是有可能被黑客入侵，因此您需要加密。如果在线服务提供了良好的空间但没有加密，您仍然可以使用VeryCrypt手动加密您的文件，然后将它们备份到云端的远程服务器。
设置数据备份的便利性和数据恢复的便利性也是一个重要问题。大多数在线备份服务都是SAAS（软件即服务(Software as a Service)），这意味着您必须下载他们的软件才能备份和恢复数据。它们主要基于HTTPS协议，不提供FTP或其他更快的协议。至少，我还没有看到任何提供FTP的在线数据备份服务。
免费在线备份服务
将数据远程备份到其他地方总是一个好习惯，这样如果本地发生任何事情，您仍然可以在某个地方备份原始数据。您可能会备份到同一房间内LAN上的另一台计算机。(LAN)但如果房间意外着火或发生类似情况，您可能会永远丢失数据。最好的方法是备份到Cloud。
当您计划使用在线备份服务时，成本是您应该考虑的一个重要因素。好消息是他们中的一些人不收你一分钱。它们完全免费供个人使用。

让我们在下面详细介绍免费服务的功能和亮点！
1] iDrive
iDrive 在我们的列表中排名第一，因为该服务为将数据传输到云端和在云端备份数据提供了加密。该驱动器的基本计划从 5 GB 的免费在线存储空间开始，当您向朋友推荐该服务时，您可以获得一些额外的空间。即使使用免费产品，您也可以享受 IDrive 高级产品的所有功能。但是，您首先需要创建一个帐户并选择使用私有加密密钥或IDrive管理的密钥（默认）。在线服务与文件资源管理器(File Explorer)完美集成。因此，您可以将其添加到右键单击上下文菜单中，以开始轻松地将项目添加到备份集中。
2]同步
对于像我这样的大多数用户来说，Syncthing 遇到了一个免费且简单的解决方案，可以将我的数据存储在Windows之外。其连续文件同步程序有助于在两个或多个设备之间安全地同步文件。该服务与其竞争对手的不同之处在于，您作为用户可以选择应存储备份的硬件。因此，您可以将备份存储在单独的计算机或硬盘驱动器、虚拟机或您选择的任何其他适用设备上。这本身为用户提供了一种管理整体安全性的强大方法，因为没有第三方托管服务参与存储您的数据。增强其安全性的其他功能包括端到端加密和基于TLS证书的身份验证。Syncthing完全免费使用！

3] 驱动器
如果您担心与成本和数据管理相关的问题，ADrive可以为您提供帮助。它很容易使用。只需使用电子邮件地址和密码进行简单的注册流程即可。登录后，您可以通过单击“我的文件”访问在线文件管理器。有一个名为Personal Basic的免费（广告支持）计划，可让您享受 50GB 的存储空间。但是，它不提供SSL加密或文件历史记录。因此，您无法恢复文件的先前版本。
4] 约塔云
在线存储服务可让您预览和编辑Office文档，并与朋友和同事实时协作。免费计划提供高达 5GB 的数据存储空间，但您可以使用所有高级功能。但是，为了获得额外空间，您需要切换到个人(Personal)计划。使用Jottacloud的一个缺点是共享选项有限。另外，没有客户端加密。您可以在手机、台式(Desktop)计算机或您选择的服务器上运行该应用程序。注册Jottacloud。
5] MiMedia
此在线存储服务提供 10 GB 的免费存储空间并提供自动备份。也就是说，MiMedia有一个很大的缺陷——它只存储多媒体文件，如照片、电影、音乐和一些文档。不备份具有.EXE 和 .ZIP文件扩展名的(file extensions)常见文件类型。(Common)
它有两种变体，一个移动应用程序和一个Windows 桌面(Windows Desktop)版本程序，允许您在线备份您的媒体文件。如果您需要更多空间，只需更改您的计划。有很多可用的选项。

Best Free Cloud-based Online Backup Services
Entrusting сompanies with questionable reputations the job of managing yоur sensitive dаta backups entails high risks. Also, the fear of sоme unknown person getting access to your data always looms large. Fortunately, a few online backup services are available to take cаre оf and the necessary steps to ensure your data is kept private and рroperly secυred. In this pоst, we’ll cover 5 Free Online Backup Services.
What to look for in cloud-based Online Backup Services
The amount of space being offered is one of the most important aspects. There are many paid options that are dedicated to back up data using HTTPS transfer, but this article will leave them out, as I intend only the free ones. Most of the online backup services offer up to 2GB of free data.
I am not counting OneDrive or Google Drive here as they are more of collaboration and share tools. Besides they do not offer encryption which is another important factor when backing up your data. Mozy, Adrive, etc., offer encryption, so your data is safe even if the remote servers are hacked. There is always a possibility of cloud services being hacked, so you would want encryption. If the online service offers good space but no encryption, you can still use VeryCrypt to encrypt your files manually and then back them up to remote servers of the cloud.
The ease of setting up data backup and ease of data restore is also an important issue. Most online backup services are SAAS (Software as a Service), meaning you have to download their software for backing up and restoring data. They are based mainly on HTTPS protocol and do not offer FTP or other faster protocols. At least, I am yet to see any online data backup service offering FTP.
Free Online Backup Services
It is always good practice to back up data remotely to some other place so that if anything happens to local place, you still have a backup of original data somewhere. You might back up to another computer on a LAN in the same room. But if the room accidentally catches fire or something similar happens, you may lose data forever. The best method is to back up to Cloud.
Cost is an important factor you should consider when you’re planning to use online backup services. The good news is some of them don’t charge you a cent. They are completely free for personal use.
- iDrive
- Syncthing
- ADrive
- Jottacloud
- MiMedia
Let’s cover the feature and highlights of the free services in a bit of detail below!
1] iDrive
iDrive secures the first position in our list because, the service offers encryption for both transferring the data to the cloud and at the cloud, where it is backed up. The drive’s basic plan starts with 5 GB of free online storage space and you get some additional space when you recommend the service to your friends. Even with the free offering, you get to enjoy all the features of IDrive’s premium offering. However, you first need to create an account and choose to either use a private encryption key or an IDrive-managed key (the default). The online service integrates well with File Explorer. So, you can add it to right-click context menu to start adding items to your backup set without hassles.
2] Syncthing
Syncthing, for most users like me, comes across a free and simple solution to store my data outside Windows. Its continuous file synchronization program facilitates the process of syncing files between two or more devices securely. What makes the service different from its rivals is the fact that you as the user get to choose the hardware where the backup should be stored. As such, you can store the backup either on a separate computer or a hard drive, virtual machine, or any other applicable device of your choosing. This itself gives users a robust way to manage the overall security as no third-party hosting service gets involved in storing your data. Other features that enhance its security include end-to-end encryption and TLS certificate-based authentication. Syncthing is completely free for use!

3] ADrive
If cost and data management-related problems worries you, ADrive can come to your rescue. It’s quite easy to use. A simple signup process with an email address and password are all that’s needed. Once logged in, you can access an online file manager by clicking on ‘My Files.’ There’s a free (ad-supported) plan called Personal Basic that lets you enjoy 50GB of storage space. However, it doesn’t offer SSL encryption or file history. As such, you cannot restore previous versions of your files.
4] Jottacloud
The online storage service lets you preview and edit Office documents, and collaborate with friends and colleagues in real-time. The free plan offers up to 5GB of data storage but you can use all the premium features. For extra space, you’ll however need to switch to a Personal plan. A downside of using Jottacloud is that the sharing options are limited. Plus, there’s no client-side encryption. You can run the application on your phone, Desktop computer, or a server of your choice. Signup for Jottacloud.
5] MiMedia
This online storage service gives out a generous 10 GB of free storage space and offers automatic backups. That said, MiMedia has one big shortfall – it only stores multimedia files like photos, movies, music, and some documents too. Common file types with.EXE and .ZIP file extensions aren’t backed up.
It comes in both variants, a mobile app and a Windows Desktop version program to allow you to back up your media files online. If you need more space, just change your plan. There are plenty of options available.
